gmayor already helped me on that (thx a lot) but now I used this macro a bit, I have few more questions on it.

The first is about what is between "With Selection.Find" and "End With". As you can see on the code, I have two of them with code between (for sure).
Is it possible to merge them ? if not, what the logic ?.

My second question.... if I track modification on word, I see that the macro highlight the word first, then erase it and replace it with non highlight word.
as consequence, the correction proposed is the non highlited word and the part corrected is the highlited word (It should be the opposit). It's not a big deal but I'm curious of the "Why"

my third question is about a possible option.
Some of my text are in french. And in French, conjugaison can be complicated.
The infinitive verb for walk is "Marcher", but the verb can be wrote "Marche", "Marché", "Marchez", "Marchons" ...etc.

On my list, I only have the infinitive. Is it possible to ask the macro to find a higligt all
"Marcher la nuit", "Marchez la nuit" and "Marchons la nuit" without writing all variant in my list of word ?
